The statement which is true about cell respiration is; Choice B: Glycolysis splits sugar to produce pyruvate and FADH2-

Definition of terms:

Cellular respiration is a process used by all living organisms to convert glucose into energy.

Cellular respiration is a collection of three unique metabolic pathways: glycolysis, pyruvate oxidation, the citric acid cycle, and the electron transport chain.

Electrons are rapidly transferred from one component to the next to the endpoint of the chain, where the electrons reduce molecular oxygen, O2 producing water in the process.

Answer:

Advantages

- Serial dilution is used in microbiology to estimate the concentration or number of cells/organisms in a sample to obtain an incubated plate with an easily countable number of colonies.

- In biochemistry, serial dilution is used to obtain the desired concentration of reagents and chemicals from a higher concentration.

- In pharmaceutical laboratories, serial dilution is performed to receive the necessary concentration of chemicals and compounds as this method is more effective than individual dilutions.

- In homeopathy, homeopathic dilutions are used where a substance is diluted in distilled water or alcohol. It is believed than dilution increases the potency of the diluted substance by activating its vital energy.

Disadvantages

- An error might occur during the propagation of the sample, and the transfer inaccuracies lead to less accurate and less precise transfer. This results in the highest dilution to have the most inaccuracies and the least accuracy.

- Because serial dilution is performed in a stepwise manner, it requires a more extended period of time which limits the efficiency of the method.

- Serial dilution only allows the reduction of bacteria/cells but not the separation of bacteria/cells like in other techniques like flow cytometry.

- This technique also requires highly trained microbiologists and experts in aseptic techniques.

Each of the spiders receive different genetic combinations from their parents, and as a result are genetically different from each other.

Explanation:

Answer:

Soil structure is defined by the way individual particles of sand, silt, and clay are assembled. Single particles when assembled appear as larger particles. These are called aggregates.

Explanation:

Aggregation of soil particles can occur in different patterns, resulting in different soil structures. The circulation of water in the soil varies greatly according to structure, Therefore, it is important for you to know about the structure of the soil where you plan to build a fish-farm. Although you may not be able to assemble all this information yourself, the specialized technicians from the soil testing laboratory will be able to provide it after examining your undisturbed soil samples. They will be able to tell you if your soil has bad structure or good structure (pores/capillary canals, network, etc.). They will also be able to tell you about the degree of water circulation or permeability.

Answer:

A nick is created between G and A in GAATTC when using Eco R1 site while a nick is generated between G and G in GGATCC when Bam H1 is used. The difference in the nicks created is the main reason you observe two bands when you digest the circular plasmid with a mixture of both

Explanation:

Circular plasmid containing : 9 kb of DNA

Eco R1 and Bam H1 are known as restriction sites in DNA ( i.e. special sequences found in a DNA ) hence they can  be specifically cleaved by the restriction enzymes enabling the insertion of a gene. that is why you will get a same result when you digest the Plasmid with either Eco R1 or Bam H1

Answer:

Totipotency

Explanation:

Totipotency can be regarded as

capability of single cell to divide,develop as well as to form differentiated cells in a living body. This could be found in Meristematic plant cells since they posses the ability to develop into complete plants. Totipotent cells can be formed during sexual and asexual reproduction and these could include spores and zygotes. Some organism can experience totipotency in the sense that cells can dedifferentiate as well as regaining totipotency. Instance of this is plant cutting which used in growing an entire plant.

Abiotic: the sunlight and water.

Biotic: Plants and insects

Explanation:

Plants such as cactuses can absorb and conserve water in their roots and use the sunlight to grow taller

Insects such as Desert beetles can trap moisture in their thick exoskeletons so they are parched or burned by the sun. They sometimes bury themselves deep in the sand where it's cooler.

The abiotic factors in the desert help the biotic factors survive

Answer:

B) greater percentage of difference in DNA sequences between sister species that inhabit deep water than between sister species that inhabit shallow water

Explanation:

The isthmus formed gradually. About 10 million years ago, the isthmus began to separate the waters from the bottom, and snapping shrimp individuals inhabiting the deepness were separated for the first time. Since their separation, both groups evolved according to their new environment and the pressures acting on them. They started to gradually differentiate from each other, probably suffering many mutations through the years.

About 3 million years ago, the oceans were completely separated by the isthmus, meaning that those animals inhabiting the shallowest areas were the last ones to separate from each other on each side of the isthmus. Since then, they probably also suffered many mutations that drove them to differentiation.  

However, as animals inhabiting the shallowest areas were the last ones to separate and, considering the time-lapse between both divergences, the highest degree of genetic difference is expressed by the sister groups inhabiting the deepest areas. Being separated from each other for a much longer time than shallow animals gave them more time to suffer more mutations and differentiate more.

The sister species at the depth of the ocean possesses a greater difference as compared to the sister species in shallow regions. Thus, option B is correct.

Evolution is the process of inheritable changes in the species with natural selection. The species in the close generation have a higher level of similarity in the traits.

The sister species are the ones with the similarity in the traits. Thus, have the same ancestors and exhibit a greater percentage of trait similarity.

Atlantic and Pacific species are sister species and have similarities in the DNA sequence.

The isthmus separation is formed later in the ocean. The species present at the deeper range are older and are evolved. The species in the shallow region have less evolution as they are separated later.

Thus, the sister species at the depth of the ocean possesses a greater difference as compared to the sister species in shallow regions. Thus, option B is correct.

Answer:

One way that the world’s ocean affects weather and climate is by playing an important role in keeping our planet warm. The majority of radiation from the sun is absorbed by the ocean, particularly in tropical waters around the equator, where the ocean acts like a massive, heat-retaining solar panel. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds. In fact, almost all rain that falls on land starts off in the ocean. The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area.

Major current systems typically flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere, in circular patterns that often trace the coastlines.

Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics.

Explanation:

One way that the world’s ocean affects weather and climate is by playing an important role in keeping our planet warm. The majority of radiation from the sun is absorbed by the ocean, particularly in tropical waters around the equator, where the ocean acts like a massive, heat-retaining solar panel. Land areas also absorb some sunlight, and the atmosphere helps to retain heat that would otherwise quickly radiate into space after sunset.

The ocean doesn't just store solar radiation; it also helps to distribute heat around the globe. When water molecules are heated, they exchange freely with the air in a process called evaporation. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds. In fact, almost all rain that falls on land starts off in the ocean. The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area.

Outside of Earth’s equatorial areas, weather patterns are driven largely by ocean currents. Currents are movements of ocean water in a continuous flow, created largely by surface winds but also partly by temperature and salinity gradients, Earth’s rotation, and tides. Major current systems typically flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere, in circular patterns that often trace the coastlines.

Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface. Without currents in the ocean, regional temperatures would be more extreme—super hot at the equator and frigid toward the poles—and much less of Earth’s land would be habitable.
